delhead [-nv] <FITS or IRAF file[s]> kw1 kw2 ... kwn
Delete keyword entries from the header of FITS or IRAF image[s]. If a keyword does not already exist, ignore it. To delete keywords in a list of files, substitute @<listfile> for the file names on the command line. To delete a lot of keywords, put them, one per line, in a file and substitute @<keylistfile> on the command line. If two @ commands are present, the program will figure out which contains file names and which contains keywords.
Write a new file with an added "e" before the extension. The default is to overwrite the input file.
